It's about as meaningful as Hillary winning some primaries late 8 years ago.
Additionally, Hillary's last few wins in 08, as with Bernie's latest wins, are more a function of the fact that the front runner had all but conceded these last few primaries.
She spent 0$ advertising in Indiana, and will do the same in Oregon, Kentucky, West Virginia, The Dakotas, Montana, and probably California and New Jersey. She knows all she has to do is win 150-200 more delegates and she's the nominee as far as the convention is concerned. There is no way that Sanders overtakes her in pledged delegates or popular vote. She can pivot to Trump without any real fear that she'll lose the nomination. Why would she waste her time or money on Bernie now?
